Title: Vacuum vessel
Inventor: NAGAI HIROAKI
IPC: G03F7/20
Filed: 1992-12-07
Abstract: PURPOSE:To allow a transmitting window to withstand atmospheric pressure even if the thickness of the window is reduced for the purpose of securing a large quantity of transmission by providing a preliminary chamber for preventing impact from being applied to the transmitting window by the difference between internal and external pressures immediately after evacuation is initiated. CONSTITUTION:A vacuum vessel 1 has an opening 3 formed through the upper portion of a vessel constituting member 2, a thin film 4 covering the opening 3 to constitute a transmitting window, and a preliminary chamber member 6, etc. The preliminary chamber member 6, the inside wall 2b of the vessel and the thin film 4 define a preliminary chamber 7 inside the vessel. The preliminary chamber member 6 has a small hole 8 bored therethrough with the conductance of the hole smaller than that of a chamber 9. Because the conductance of the small hole 8 between the preliminary chamber 7 and the chamber 9 is small immediately after evacuation is initiated, pressure within the preliminary chamber 7 is slowly varied and the pressure difference between the inside and outside of the transmitting window 4 is reduced accordingly, so the thickness of the transmitting window 4 can be reduced.

IPC: H02K29/08
Filed: 1991-11-15
Abstract: PURPOSE:To obtain self-starting means for a low-cost contactless DC motor with a simple construction and a small size. CONSTITUTION:This motor comprises a permanent magnet rotor having n- magnetic pole, a flux plate 12 made of a magnetic material located in opposite to the rotor, a Hall element 14 for detecting the rotation position of rotor magnetic pole, a coil 13 for giving a rotating force to a rotor magnetic pole during current application, and a notch formed at the position other than the position of Hall element of the flux plate and every position 360 deg./n far from the Hall position. When the rotor stops, the magnetic neutral point between magnetic poles is stopped at the position in opposite to the notch. At this time, the Hall element is always on the magnetic pole and not at the magnetic neutral point, so that the magnetism can be detected and the rotor can be rotated by applying the current to the coils.

Title: Formation of metal-hydrogen alkaline storage battery
Inventor: TADOKORO MIKIAKI
IPC: H01M4/26
Filed: 1989-12-15
Abstract: PURPOSE:To complete a formation process in a short time and reduce the manufacturing cost by providing a process for penetrating electrolyte into gaps in an outer electrode composing active material and fine cracks of hydrogen storage alloy with alkaline electrolyte included. CONSTITUTION:A process of penetrating electrolyte into gaps in an outer electrode composing active material and fine cracks of hydrogen storage alloy with alkaline electrolyte included. The cracks are produced in the hydrogen storage alloy because hydrogen penetrates into crystal grids of the alloy at the time of the first charge, so the surface area of the alloy is increased. As a result, the electrolyte penetrates into the cracks to increase the reaction surface area, so activation is performed. A formation process can thus be performed in a short time, thereby the manufacturing cost of a battery can be reduced.

Title: Satellite communication system and transmitter
Inventor: OI TOMOYUKI
IPC: H04B7/208
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To perform the control of a reception frequency without depending on the shift frequency of a satellite to be used. SOLUTION: The frequency band to be the one unity of carrier ID is made wider than an AFC range, is made 200kHz to the one and half times as many as 1MHz and 80 carrier ID of (=200[kHz]/2.5[kHz]) are assigned. Thus, in the reception frequency band of 12. 27GHz or more, the carrier ID and a reception frequency can be matched when a JCSAT is used and when a superbird is used. Therefore, an AFC control can be performed for the reception signal by a common firmware without generating the erroneous synchronization due to the difference of the shift frequency of a satelliate to be used in a satellite receiver.

Title: Manufacture of compound semiconductor device
Inventor: KUSANO CHUSHIRO
IPC: H01L21/338
Filed: 1987-12-25
Abstract: PURPOSE:To enable a selectively deposited layer even in thickness of deposited film to be formed by a method wherein recessions not reaching the crystal surface or projections are formed into dummy patterns on a protective film. CONSTITUTION:The surface of a compound semiconductor 10 is covered with a protective film such as SiO2, Si3N4, WSix, etc., to form a selectively deposited regular pattern 11 and then recessions not reaching the substrate crystal surface or projections are formed into dummy patterns 12 on the peripheral part of the regular pattern 11. In other words, when GaAs is selectively deposited on the regular pattern 11 isolated in wide space, the film thickness is abnormally increased but when the dummy patterns 12 taking the same shape as that of the regular pattern 11 are evenly distributed, the thickness of the deposited film is made even. Furthermore, if the recessed dummy patterns 12 around the regular pattern 11 are formed not to reach the substrate crystal surface, any needless crystal deposited layer is not formed by the dummy patterns 12 to prevent the later manufacturing processes from being restricted.

Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a balance with high speed, high accuracy, and a low cost by using electromagnetic braking by eddy current. SOLUTION: When a measuring object 2 is placed on a measuring stand 3, a level 1 starts to move from a reference position S1, moves in the arrow F direction in accompany with the deformation of a spring fulcrum 5 fixed to a lever support 4, repeats up and down vibrations, and then equilibrates and stops in the position of the displacement S2 according to weight. The displacement S2 is measured with a capacitance meter 6 to measure weight. When the lever 1 moves in the arrow F direction by placing the measuring object on the stand 3 and shock by outside vibration, a diamagnetic material conductor 9 fixed to the lever 1 cuts the line of magnetic force 8 emitted from a magnet 7 fixed to the lever support 4, eddy current is generated in the conductor, and braking force in the direction opposite to the arrow F direction acts to the level 1.  When the lever 1 is moved in the direction opposite to the arrow F direction, the braking force is induced in the direction opposite to the above mentioned direction by the same electromagnetic action, and the lever 1 quickly stops at the displacement S2 of an equilibrium point.

IPC: G11B20/00
Filed: 1991-12-11
Abstract: PURPOSE: To improve burst error correcting capability by interleaving two fields in one frame alternately in internal code length units and diffusion an error ever two fields. CONSTITUTION: A frame interleaving part 200 reads data of odd numbered fields and even numbered fields coded by an external error correction code part 100 by internal codes and arrays them so that they cross each other. An internal error correction code part 300 after adding vertical additional information to data outputted from the frame interleaving part 200 transmits it progressively. An internal error correction and decoding part 900 corrects an error within the correcting capability if the error occurs to demodulated data, but adds an error flag to an error exceeding the correcting capability. A frame deinterleaving part 1000 retrieves the data and transmits the corresponding odd numbered or even numbered field data in external code units.
